ROOF-CARLINE.

Specification of Letters Patent. Patented Sept. 21, 1909. Applicationfiled July 27, 1909. Serial No. 509,761.

To all whom it may camera:

Be it known that I, ALBERT G. ELVIN, of East Orange, in the county ofEssex and State of New Jersey, have invented a certain new and usefulImprovement in Roof-Carlines, of which improvement the following is aspecification.

The object of my invention is to provide a metallic roof carline whichshall embody the features of strength, lightness, and specialadaptability for use in the framing of railroad cars.

The improvement fully set forth.

In the accompanying drawings: Figure 1 is an end view of a structuralshape, (a T rail) adapted for use in the manufacture of a roof carlineembodying my invention; Fig. 2, a side view, in elevation, of a portionof the same; Fig. 3, an end view of a T section shape produced bytransversely severing the web of the shape shown in Fig. 1; Fig. 4, anend view of another structural shape (in claimed is hereafter this casean I beam) adapted for use in the manufacture of a roof carlineembodyingmy invention; Fig. 5, a side view, in elevation,

of a portion of the same; Fi 6, end views of two T section shapesproduced by transversely severing the web of the shape shown in Fig. 45;Fig. 7, a side View, in elevation, of slightly more than one half of thelength of a roof carline produced from a T sectlon shape of Figs. 3 and6, and embodying my invention; Fig. 8, a plan or top viewof the same;Fig. 9, a transverse section, on the line a a of Fig. 7 Fig. 10, an endview, in elevation; and, Fig. 11, a transverse section on the line b bof Fig. 7.

In the manufacture of a roof carline embodying my invention, I take arolled shape which presents, in transverse section, a web and endlateral enlargements or flanges, .as, for example, a T rail, Figs. 1 and2, or an I beam. Figs. 4 and 5, and, after having heated the rolledshape to a proper temperature, sever the web transversely at or aboutthe middle of its depth, thereby producing two portions of T section, asshown in Figs. 4 and 6. In the case of a T rail, while both theresulting portions may be correctly said to be of T section, that whichcontains the head of the rail will, of course, have a narrower andheavier base than the other, while, in the case of an I beam, theportions will both be of strictly T section, and of substantiallysimilar sectional form and area. The T sectionshape thus produced isthen passed between suitably grooved rolls, which may be done either inthe same or a subsequent heat, as may be found most desirable, androlled into a roof carline, which, when finished, is of the form shownin Figs. 7 to 11 inclusive.

The body, 1, of the carline, is of channel section, its side flangesbeing turned upwardly, and is bent downwardly from its middle towardeach of its ends, in accordance with the pitch or inclination of .theroof in which it is to be used. An integral central strengthening rib,1, projects downwardly from the lower side of the body, 1, said ribbeing of maximum depth at, and for some distance on each sideof, themiddle thereof, and thence gradually decreasing in depth toward the endsof the body, near which it terminates. The ends of the body are widenedout and turned downwardly into transversely extending end flanges, 1which are provided for attachment to the ordinary side plates of acarframe. The space between the. side flanges of the body may-beutilized for the reception of a wood filler.

The advantages of my invention in the economical utilization of worn ordiscarded rolled shapes of the character specified, for

the production of a roof carline which is I and decreasing in depth fromthe middle P01.

tion of the body toward each of the ends thereof.

As a new article of manufacture, .a

5 metal roof carline having a body of channel section, an integralcentral strengthening rib" projecting downwardly from the body, and

transversely extending end flanges turned downwardly on the body.
